Hello,  
I am having som troubles instlling the discourse calendar plugin.

Any ideas what could be the problem?  
Attached the whole html error report. Here a extract with the error:

```plaintext
ERROR: While executing gem … (Errno::ENOENT)
No such file or directory @ rb_sysopen - /home/discourse/.local/share/gem/ruby/2.7.0/cache/rrule-0.4.4.gem

You are specifying the gem rrule in /opt/bitnami/discourse/plugins/discourse-calendar/plugin.rb, however it does not exist!
Looked for: /opt/bitnami/discourse/plugins/discourse-calendar/gems/2.7.5/specifications/rrule-0.4.4.gemspec
Error: The application encountered the following error: exit (SystemExit)

```
